Flat Top Grill Question

I've just got my flat top in and I'm going to be opening my restaurant in a few days and I've got a question about tempature. I'm going to be cooking fresh ground beef burgers well done and I need to get them cooked all the way through without burning the outside and without taking a half hour to cook. Anyone have any suggestions on a good cooking tempature to start at or any tips or tricks to working on a flat top grill? Also, what type of oil do you recommend using? I was thinking of using lard.

Any ideas will be greatly apprciated.

Thanks in advance,
Will

350 degrees. good way to season new flat top is cook good amount bacon on it spread grease around after then let sit about 10 minutes and scrape clean.

spud is right. You must season it first. Think of it as a new cast-iron skillet.

All well done? If so, why. 350 is good, flip them once, turning the burger 180 degrees on the flip, use a rounded end spatula, slide it under both sides of the burger before sliding it to the middle of the burger to turn, it keeps any of the meat from sticking to your top, never press on the burger as you will press out the flavor via the juice. I recommend salt, pepper, granulated garlic, on burgers, on the side up right after you GENTLY lay the burgers on the flat top, helps to keep the meat from sticking. if you can, hand patty them.
